[BUG] Update not working

[Hqrshy]

I attempted to update Migaku to the latest update but it did not function instead it just said it failed.

To Reproduce
Steps to reproduce the behavior:

1. Go to Anki
2. Click on Update All
3. Press Okay
4. Wait for Update to finish
5. See error

The update would have been successfully installed if everything worked properly.
